The sulphur-bellied bulbul is a songbird species in the bulbul family, Pycnonotidae. It is endemic to Palawan (Philippines). Its natural habitat is tropical moist lowland forests.
Region
Southeast Asia
Typical Environment
Endemic to the Palawan biogeographic region, occurring on the main island of Palawan and nearby islands such as Busuanga and Culion. It inhabits tropical moist lowland evergreen forests, riverine forests, and forest edges. The species is most frequently found in the midstory and canopy, but also ventures into well-vegetated secondary growth. It can persist in selectively logged areas if fruiting trees remain, though it is less common outside intact forest.

The sulphur-bellied bulbul is confined to the Palawan region of the Philippines and plays an important role as a seed disperser in tropical forests. It often joins mixed-species flocks and forages quietly in the midstory, making it easier to hear than to see. While it tolerates some secondary growth, it depends on healthy lowland forests, so habitat loss is its main threat.
